For control of space debris of both artificial and natural (asteroid) origin, the ground-based optical array was proposed. Image processing algorithms in the ground aperture synthesis array are proposed and studied. Considering 'island' nature array OTF showed that our modified method version of triple correlations is optimal for phase locking of spatial spectrum from the object between 'islands' and the iterational algorithm for the equation evolvent of the locked phases is proposed for the phase restoration. The experimental research of perspective technologies for image forming and processing in a ground-based aperture synthesis array was carried out by the methods of physical and machine simulation. The results of model experiment confirmed the efficiency of proposed perspective technologies for reaching of high angular resolution.
